Multi-Package Shipments
Why use multi-package shipping?
When you use multi-package shipping, you’re able to group packages, get discounted rates, and retrieve a one to many “master” tracking number.
Carrier Support
Not all carriers, and not all services support multi-package shipping. To learn which services support multi-package check the is_multi_package_supported
property when making a List Carriers or List Carrier Services call.
Current carriers that have Multi-Package services include: FedEx, UPS, DHL Express, DHL Express Canada, DHL Express UK, FirstMile, Purolator Canada.
Package Types
All multi-package shipment labels created via ShipEngine will use the standard package type of package
. This is because carrier-specific packaging is not widely supported by carriers for multi-package shipping.
Rate requests for multi-package shipments that include carrier-specific package types may return rates. However, any labels created from the quoted rates will update the package type to package
.

Label Downloads
We consolidate all of the labels for a multi-package shipment into a multi-page PDF or ZPL file. Currently, we don't support the PNG format for multi-package shipments.

This is the master tracking label, the first label in the series.

The second label also includes the Master Tracking number on it.
